Cultural aspects of preschool education: Ojibwa, Odawa and Potawatomi Indian children\u27s \u27\u27ways of knowing and communicating\u27\u27 in early intervention and Head Start programs
This research investigated what Anishinabe cultural values and beliefs are transmitted in the Head Start and Early Head Start oft he Inter-Tribal Council of Michigan, and how Anishinabe values and beliefs affect instructional communications, teacher/student relationships, and the learning styles used by Native teachers in the educational process of Anishinabe children in the preschool situation. The study used an ethnographic approach to identify what informants would describe was their culture among the four Inter-Tribal Preschool programs. Observations completed in the classroom, home and community environment sought to discover how parents, teachers, children and staff in the preschool process use the culture. Outreach to interview Elders and grandparents from each of the four communities were an important component of this research in reconstructing the aboriginal culture and Tribal history
A Descriptive Study of Nosocomial Infections in an Adult Intensive Care Unit in Fiji: 2011-12

Nosocomial infections in an intensive care unit (ICU) are common and associated with a high mortality but there are no published data from the Oceania region. A retrospective study in Fiji’s largest ICU (2011-12) reported that 114 of a total 663 adult ICU admissions had bacteriological culture-confirmed nosocomial infection. The commonest sites of infection were respiratory and bloodstream. Gram negative bacteria were the commonest pathogens isolated, especially Klebsiella pneumoniae (extended-spectru
Isotope shift measurements in the 2s1/2 → 2p3/2 transition of Be+ and extraction of the nuclear charge radii for 7,10,11Be
We have performed isotope shift measurements in the 2s1/2 → 2p3/2 transition of Be+ ions using advanced collinear laser spectroscopy with two counter-propagating laser beams. Measurements involving a frequency comb for laser stabilization and absolute frequency determination allowed us to determine the isotope shifts with an accuracy of 2 MHz. From the isotope shifts between 9Be and 7, 10, 11Be, high-accuracy mass shift calculations and the charge radius of the reference isotope 9Be we determined nuclear charge radii for the isotopes 7, 10Be and the one-neutron halo nucleus 11Be. The results are compared to nuclear-structure calculations using the fermionic molecular dynamics model which reproduce well the general trend of the radii. Decreasing charge radii from 7Be to 10Be are explained by the cluster structure of the nuclei. The increase from 10Be to 11Be is mainly caused by the halo neutron by which the 10Be core moves relative to the center of mass. Polarization of the 10Be core has only a small influence on the charge radius. © 2010 IOP Publishing Ltd
A full field simulation of the in Salah gas production and CO2 storage project using a coupled geo-mechanical and thermal fluid flow simulator
AbstractWe report results from a full field simulation model of the combined production and injection reservoirs, extending from a depth of 3.5Â km to ground level, and with a lateral, x and y, extent of approximately 50Â km. The model couples geomechanical calculations to fluid flow with an energy transport equation. It simulates two-phase immiscible flow with four components (CH4, CO2, NaCl and H2O) in the gas and aqueous phases. CO2 may dissolve into the aqueous phase. Fractures are modelled explicitly in the grid
The Union and Médecins Sans Frontières approach to operational research.
Operational research (OR) has become a hot topic at national meetings, international conferences and donor fora. The International Union Against Tuberculosis and Lung Disease (The Union) and Médecins Sans Frontières (MSF) Operational Centre Brussels strongly promote and implement OR with colleagues in low- and middle-income countries. Here we describe how the two organisations define OR, and explain the guiding principles and methodology that underpin the strategy for developing and expanding OR in those countries. We articulate The Union's and MSF's approach to supporting OR, highlighting the main synergies and differences. Then, using the Malawi National Tuberculosis Control Programme as an example, we show how OR can be embedded within tuberculosis control activities, leading to changes in policy and practice at the national level. We discuss the difficult, yet vitally important, issue of capacity building, and share our vision of a new paradigm of product-related training and performance-based OR fellowships as two ways of developing the necessary skills at country level to ensure research is actually performed. Finally, we highlight the need to consider and incorporate into practice the ethical components of OR. This is a key moment to be involved in OR. We are confident that in partnership with interested stakeholders, including the World Health Organization, we can stimulate the implementation of quality, relevant OR as an integral part of health service delivery that in turn will lead to better health for people, particularly for those living in the poorer parts of the world
A new beamline for laser spin-polarization at ISOLDE
A beamline dedicated to the production of laser-polarized radioactive beams
has been constructed at ISOLDE, CERN. We present here different simulations
leading to the design and construction of the setup, as well as technical
details of the full setup and examples of the achieved polarizations for
several radioisotopes. Beamline simulations show a good transmission through
the entire line, in agreement with observations. Simulations of the induced
nuclear spin-polarization as a function of atom-laser interaction length are
presented for Na, [1] and for Ar, which is studied in this
work. Adiabatic spin rotation of the spin-polarized ensemble of atoms, and how
this influences the observed nuclear ensemble polarization, are also performed
for the same nuclei. For Ar, we show that multiple-frequency pumping
enhances the ensemble polarization by a factor 1.85, in agreement with
predictions from a rate equations model.
